What is an example from the Qur’an of disbelief that only constitutes major disbelief that expels one from the fold of Islam?

In the Noble Quran, the term "kufr" (disbelief/rejection) is used in five different senses: 1. Kufr pertaining to monotheism and faith (major kufr): This is the most common usage in the Quran. 2. Ungratefulness for blessings. 3. Disassociation. 4. Denial. 5. Covering (like the work of farmers).

There are many verses that address major kufr, including: "Indeed, disbelievers are those who say, 'Allah is the Messiah, son of Mary,'" and "Indeed, disbelievers are those who say, 'Allah is the third of three,'" and "Whoever disbelieves in Allah after his belief, except for one who is compelled."
